GMFRs of Pneumococcal Serotype-Specific Opsonophagocytic Activity (OPA) Titers for the 7 Additional Serotypes From Before to 1 Month After 20vPnC Vaccination: Cohort 3 and 4Before vaccination on Day 1 to 1 month after vaccinationPneumococcal serotype-specific OPA titers were measured from serum samples for 7 the additional 20vPnC serotypes: 8, 10A, 11A, 12F, 15B, 22F and 33F. GMFR = geometric mean of fold rise from before vaccination on Day 1 to 1 month after vaccination with 20vPnC. GMFRs and the corresponding 2-sided 95% CIs were calculated by exponentiating the mean logarithm of fold rises and the corresponding 2-sided 95% CIs (based on the Student's t distribution). Superiority of OPA titers 1 month after 20vPnC to before vaccination for each serotype was demonstrated if the 95% lower CI of the GMFR was \>1.
Percentage of Participants Reporting Prompted Local Reactions Within 7 Days After VaccinationWithin 7 days after vaccination on Day 1Local reactions included redness, swelling and, pain at the injection site, recorded by parent's/legal guardians of participants in an electronic diary (e-diary). Redness and swelling were measured and recorded in measuring device units. One measuring device unit =0.5 centimeter (cm). Redness and swelling were graded as mild: \> 0.0 to 2.0 cm, moderate: \>2.0 to 7.0 cm and severe: \>7.0 cm. Pain at the injection site was graded as mild: hurt if gently touched (cohort 1) and did not interfere with activity (cohort 2-4); moderate: hurt if gently touched with crying (cohort 1) and interfered with daily activity (cohort 2-4) and; severe: limited limb movement (cohort 1) and prevented daily activity (cohort 2-4). 95 percent (%) confidence interval (CI) was based on Clopper and Pearson method.
Percentage of Participants Reporting Prompted Systemic Events Within 7 Days After Vaccination: Cohort 1Within 7 days after vaccination on Day 1Systemic events for Cohort 1 included fever, decreased appetite, drowsiness/increased sleep and irritability, recorded by parents/legal guardians of participant's using an e-diary. Fever was defined as temperature \>=38.0 degrees Celsius (C) and categorized as \>=38.0 to 38.4 degrees C, \>38.4 to 38.9 degrees C, \>38.9 to 40.0 degrees C and \>40.0-degrees C. Decreased appetite was graded as mild (decreased interest in eating), moderate (decreased oral intake) and severe (refusal to feed). Drowsiness was graded as mild (increased or prolonged sleeping bouts), moderate (slightly subdued, interfered with daily activity) and severe (disabling, not interested in usual daily activity). Irritability: graded as mild (easily consolable), moderate (required increased attention) and severe (inconsolable, crying could not be comforted). 95% CI was based on Clopper and Pearson method.
Percentage of Participants Reporting Prompted Systemic Events Within 7 Days After Vaccination: Cohorts 2, 3 and 4Within 7 days after vaccination on Day 1Systemic events for Cohort 2-4 included fever, fatigue, headache, muscle pain and joint pain, recorded by parents/legal guardians of participant's using an e-diary. Fever was defined as temperature \>=38.0 degrees C and categorized as \>=38.0 to 38.4 degrees C, \>38.4 to 38.9 degrees C, \>38.9 to 40.0 degrees C and \>40.0 degrees C. Fatigue, headache, muscle pain and joint pain were graded as mild (no interference with activity), moderate (some interference with activity) and severe (prevents daily routine activity). 95% CI was based on Clopper and Pearson method.
Percentage of Participants Reporting Adverse Events (AEs) up to 1 Month After VaccinationFrom vaccination (on Day 1) up to 1 month after vaccinationAn AE was any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. 95% CI was based on the Clopper and Pearson method. Only AEs collected by non-systematic assessment (i.e. excluding local reactions and systemic events) were reported in this outcome measure.
Percentage of Participants Reporting Serious Adverse Events (SAEs) up to 6 Months After VaccinationFrom vaccination (on Day 1) up to 6 months after vaccinationAn SAE was any untoward medical occurrence that occurred, at any dose: resulted in death; required inpatient hospitalization or prolongation of existing hospitalization; was life-threatening; resulted in persistent or significant disability/ incapacity; was a congenital anomaly/birth defect and other important medical events. 95% CI was based on the Clopper and Pearson method.
Percentage of Participants Reporting Newly Diagnosed Chronic Medical Conditions (NDCMCs) up to 6 Months After VaccinationFrom vaccination (on Day 1) up to 6 months after vaccinationAn NDCMC was defined as a disease or medical condition, not previously identified, that was expected to be persistent or was otherwise long-lasting in its effects. 95% CI was based on the Clopper and Pearson method.
Geometric Mean Fold Rises (GMFRs) of Pneumococcal Serotype-Specific Immunoglobulin G (IgG) Concentrations for the 7 Additional Serotypes From Before to 1 Month After 20vPnC Vaccination: Cohort 1 and 2Before vaccination on Day 1 to 1 month after vaccinationPneumococcal serotype-specific IgG concentrations were measured from serum samples for the 7 additional 20vPnC serotypes: 8, 10A, 11A, 12F, 15B, 22F and 33F. GMFR = geometric mean of fold rise from before vaccination on Day 1 to 1 month after vaccination with 20vPnC. GMFRs and corresponding 2-sided 95% CIs were calculated by exponentiating the mean logarithm of fold rises and the corresponding 2-sided 95% CIs (based on Student's t distribution). Superiority of IgG concentration 1 month after 20vPnC to before vaccination for each serotype was demonstrated if the 95% lower CI of GMFR was \>1.

Geometric Mean Fold Rises (GMFRs) of Pneumococcal Serotype-Specific Immunoglobulin G (IgG) Concentrations for the 7 Additional Serotypes From Before to 1 Month After 20vPnC Vaccination: Cohort 1 and 2

Pneumococcal serotype-specific IgG concentrations were measured from serum samples for the 7 additional 20vPnC serotypes: 8, 10A, 11A, 12F, 15B, 22F and 33F. GMFR = geometric mean of fold rise from before vaccination on Day 1 to 1 month after vaccination with 20vPnC. GMFRs and corresponding 2-sided 95% CIs were calculated by exponentiating the mean logarithm of fold rises and the corresponding 2-sided 95% CIs (based on Student's t distribution). Superiority of IgG concentration 1 month after 20vPnC to before vaccination for each serotype was demonstrated if the 95% lower CI of GMFR was \>1.

Time frame: Before vaccination on Day 1 to 1 month after vaccination

Population: Evaluable immunogenicity population (EIP) included all participants who were eligible; received 20vPnC; at least 1 valid immunogenicity result from 1 month after vaccination collected within 27 to 56 days after vaccination for Cohorts 1-2; no other major protocol deviations. Here, Number of Participants Analyzed signifies participants evaluable for this outcome measure and 'Number Analyzed' signifies participants with valid assay results at both timepoints for the specified serotype.

Percentage of Participants Reporting Prompted Local Reactions Within 7 Days After Vaccination

Local reactions included redness, swelling and, pain at the injection site, recorded by parent's/legal guardians of participants in an electronic diary (e-diary). Redness and swelling were measured and recorded in measuring device units. One measuring device unit =0.5 centimeter (cm). Redness and swelling were graded as mild: \> 0.0 to 2.0 cm, moderate: \>2.0 to 7.0 cm and severe: \>7.0 cm. Pain at the injection site was graded as mild: hurt if gently touched (cohort 1) and did not interfere with activity (cohort 2-4); moderate: hurt if gently touched with crying (cohort 1) and interfered with daily activity (cohort 2-4) and; severe: limited limb movement (cohort 1) and prevented daily activity (cohort 2-4). 95 percent (%) confidence interval (CI) was based on Clopper and Pearson method.

Percentage of Participants Reporting Prompted Systemic Events Within 7 Days After Vaccination: Cohort 1

Systemic events for Cohort 1 included fever, decreased appetite, drowsiness/increased sleep and irritability, recorded by parents/legal guardians of participant's using an e-diary. Fever was defined as temperature \>=38.0 degrees Celsius (C) and categorized as \>=38.0 to 38.4 degrees C, \>38.4 to 38.9 degrees C, \>38.9 to 40.0 degrees C and \>40.0-degrees C. Decreased appetite was graded as mild (decreased interest in eating), moderate (decreased oral intake) and severe (refusal to feed). Drowsiness was graded as mild (increased or prolonged sleeping bouts), moderate (slightly subdued, interfered with daily activity) and severe (disabling, not interested in usual daily activity). Irritability: graded as mild (easily consolable), moderate (required increased attention) and severe (inconsolable, crying could not be comforted). 95% CI was based on Clopper and Pearson method.

Percentage of Participants Reporting Serious Adverse Events (SAEs) up to 6 Months After Vaccination

An SAE was any untoward medical occurrence that occurred, at any dose: resulted in death; required inpatient hospitalization or prolongation of existing hospitalization; was life-threatening; resulted in persistent or significant disability/ incapacity; was a congenital anomaly/birth defect and other important medical events. 95% CI was based on the Clopper and Pearson method.

Time frame: From vaccination (on Day 1) up to 6 months after vaccination

Population: Safety population included all participants who received 20vPnC and had safety follow-up after vaccination.

Secondary

Geometric Mean Concentrations (GMCs) of Pneumococcal Serotype-Specific IgG for the 20vPnC Serotypes Before and 1 Month After Vaccination

Pneumococcal serotype-specific IgG concentrations were measured for serum samples for 13vPnC serotypes: 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F; and 7 additional 20vPnC serotypes: 8, 10A, 11A, 12F, 15B, 22F and 33F. GMCs the corresponding 2-sided 95% CIs were calculated by exponentiating the mean logarithm of the concentrations and the corresponding 2-sided 95% CIs (based on the Student's t distribution).

Time frame: Before vaccination and 1 month after vaccination

Population: EIP included all participants who were eligible; received 20vPnC; at least 1 valid immunogenicity result from 1 month after vaccination collected within 27 to 56 days or within 27 to 49 days after vaccination for Cohorts 1-2 or Cohorts 3-4, respectively; no other major protocol deviations. Here, Number of Participants Analyzed signifies participants included in the EIP and Number Analyzed signifies participants with valid IgG concentrations at the specified timepoint for specified serotype.

Geometric Mean Titers (GMTs) of Pneumococcal Serotype-Specific OPA Titers for the 20vPnC Serotypes Before and 1 Month After Vaccination

Pneumococcal serotype-specific OPA titers were measured from serum samples for 13vPnC serotypes: 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F; and 7 additional 20vPnC serotypes: 8, 10A, 11A, 12F, 15B, 22F and 33F. GMTs and 2-sided 95% CIs were calculated by exponentiating the mean logarithm of the titers and the corresponding 2-sided 95% CIs (based on the Student's t distribution). OPA titers were measured in a randomized subset of serum samples in Cohorts 1 and 2. OPA titers for the 13vPnC serotypes were measured in a randomized subset of serum samples in Cohorts 3 and 4.

Time frame: Before vaccination on Day 1 and 1 month after vaccination

Population: EIP included all participants who were eligible; received 20vPnC; at least 1 valid immunogenicity result from 1 month after vaccination collected within 27 to 56 days or 27 to 49 days after vaccination for Cohorts 1-2 or Cohorts 3-4, respectively; no other major protocol deviations. Here, Number of Participants Analyzed signifies participants evaluable for this outcome measure and Number Analyzed signifies participants with valid OPA titers at the specified timepoint for specified serotype.

GMFRs of Pneumococcal Serotype-Specific IgG Concentrations for the 13vPnC Serotypes From Before to 1 Month After Vaccination: Cohort 1 and 2

Pneumococcal serotype-specific IgG concentrations were measured from serum samples for 13vPnC serotypes: 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F. GMFR = geometric mean of fold rise from before vaccination on Day 1 to 1 month after vaccination with 20vPnC. GMFRs and the corresponding 2-sided 95% CIs were calculated by exponentiating the mean logarithm of the fold rises and the corresponding 2-sided 95% CIs (based on the Student's t distribution).

Time frame: Before vaccination on Day 1 to 1 month after vaccination

Population: EIP included all participants who were eligible; received 20vPnC; at least 1 valid immunogenicity result from 1 month after vaccination collected within 27 to 56 days after vaccination for Cohorts 1-2; no other major protocol deviations. Here, Number of Participants Analyzed signifies participants evaluable for this outcome measure and Number Analyzed signifies participants with valid assay results at both timepoints for the specified serotype.
